HANDLE FOR STEAM ANDKOTHER VALVES.

SPECIFICATION forming part of Letters Patent No. 290,575, dated December18, 1883.

Application filed January 29, 1883. (No model.)

I0 all whom t may concern.:

Be it known that I, HENRY M. HALL, a citizen of the United States,residing in the city and county of Philadelphia, State of vPennsylvania,have invented a new and useful kImprovement `in Handles for Steam andother Valves liable to be heated, which improvement is fully set forthinthe following specication and accompanying drawings, in which- Figurel is a top or plan view of a valvehandle embodying my invention. Fig. 2is a section thereof in line x fr, Fig. 1.A Figs. 3 and Il are sideelevations of modifications.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists in providing the handle of a valve liable to heheated with means, substantially as hereinafter set forth, whereby inoperating the valve the hand is guarded and prevented from being burned.

Referring to the drawings. A represents the handle of a valve liable tobe heated by steam or other hot iiuid admitted to said valve, saidhandle being of the form of an annulus or wheel. The periphery ofthehandle is grooved, as at a. and in the groove is fitted a band, B, ofrubber-apocr conductor of heat-which rnily retains its position in thegroove, and is of such width as to project outwardly beyond theperipheral edge of the handle.

It will be seen that when the valve is to be opened or closed the handof the operator is placed in Contact with the band B, and the powerexerted thereon is communicated to the handle,whereby the latter isrotated, as usual.

and produce results similar to those hereinbev l It is well known thatwhen the handle of a heated valve is graspedthe palm of the hand is mostliable to be burned, owing to the pressnre of the saine on the handleand its sensitiveness; This is avoided by the projecting portion of theband,which removes the palm from the metal of the handle, and,ifproperly grasped, may also reinovetheiingers therefrom, thus guiding thehand and preventing bnrning thereof, a better hold of the handle being45 also obtained.

- The groove a may be rectangular, round, or dovetailed incross-section, and the band similarly shaped; or wh en stretched orsprung into y the groove the contiguous portion may asvsonne the shapeofthe groove.

For handles such as are shown in Figs. 3 and 4 the sides may be groovedlongitudinally or transversely to receive one or more bands,

5E fore stated.

Having thus described niy invention, what I claim as new, and desire tosecure by Letters Patent, isy The handle of a valve,provided with aguard consisting of a rubber band, which is fitted in a peripheralgroove of the same, substantially as and for the purpose set forth.

HENRY M. HALL.
